# Gregorian, Jalali & Hijri - Angular Event calendar demo
Show events in Gregorian, Jalali, or Hijri with the Angular event calendar — switch between calendar systems to support Persian.
- [Live demo](https://demo.mobiscroll.com/angular/eventcalendar/gregorian-jalali-hijri)
- [View code on GitHub](https://github.com/acidb/mobiscroll-demos-angular/tree/main/src/demos/eventcalendar/calendar-view/gregorian-jalali-hijri)
- This demo in other frameworks: [JavaScript](https://demo.mobiscroll.com/javascript/eventcalendar/gregorian-jalali-hijri.md), [jQuery](https://demo.mobiscroll.com/jquery/eventcalendar/gregorian-jalali-hijri.md), [React](https://demo.mobiscroll.com/react/eventcalendar/gregorian-jalali-hijri.md), [Vue](https://demo.mobiscroll.com/vue/eventcalendar/gregorian-jalali-hijri.md)
## Description
The event calendar supports multiple calendar systems. You can control it with the [`calendarSystem`](https://mobiscroll.com/docs/angular/eventcalendar/api#localization-calendarSystem) setting, and it supports the following options:
- **Gregorian** - it is included by default
- **Jalali** - it is the default system of the Persian calendar and is included within the Farsi language pack
- **Hijri** - it is included in the Arabic language pack

## What this demo shows
- A desktop month-view event calendar with a segmented control for switching between Gregorian, Jalali, and Hijri calendar systems.
- **Calendar system picker** The left side of the calendar shows a "Pick a calendar system" label with three options, where Gregorian is selected by default and choosing another option (Jalali or Hijri) updates the calendar system.
- **Calendar header** The header shows the current month and year on the left, and blue month navigation arrows with a `Today` button (for jumping back to the current date) between them on the right.
- **Event labels** Day cells render events as labels with different colors and styles to distinguish all-day, multi-day, and timed events.
- **Overflow handling** The number of visible event labels depends on the available height in each day cell. Additional events are collapsed behind an `X more` link.
- **Popover** Clicking the `X more` link opens a popover that shows the hidden events for that day.
- **Label interaction** Hovering over or clicking an event label selects it and highlights the selected label.
- **Day cell states for future days** Hovering a day cell highlights the day number with a gray background, while clicking the empty part of the cell selects the day and highlights the day number with a blue background.
- **Month navigation** The month can be changed either with the header arrows or by clicking and dragging the calendar left or right.
## Best for
- **Regional user experiences** Products that need to present dates in the calendar system users already rely on, such as Gregorian for international audiences, Jalali for Persian-speaking users, or Hijri for Arabic-speaking users.
- **Localized scheduling flows** Booking, planning, and event management interfaces where users need to browse months, review events, and select dates in a familiar calendar system.

## Code
### Component
```ts
import { CommonModule } from '@angular/common';
import { HttpClient } from '@angular/common/http';
import { Component, OnInit } from '@angular/core';
import {
hijriCalendar,
jalaliCalendar,
localeAr,
localeEn,
localeFa,
MbscCalendarEvent,
MbscEventcalendarOptions,
MbscModule,
setOptions,
} from '@mobiscroll/angular';
setOptions({
theme: 'ios',
themeVariant: 'light'
});
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
standalone: true,
imports: [CommonModule, MbscModule],
})
export class AppComponent implements OnInit {
constructor(private http: HttpClient) {}
myEvents: MbscCalendarEvent[] = [];
gregorianOptions: MbscEventcalendarOptions = {
locale: localeEn,
};
jalaliOptions: MbscEventcalendarOptions = {
calendarSystem: jalaliCalendar,
locale: localeFa,
};
hijriOptions: MbscEventcalendarOptions = {
calendarSystem: hijriCalendar,
locale: localeAr,
};
ngOnInit(): void {
this.http.jsonp('https://trial.mobiscroll.com/events/?vers=5', 'callback').subscribe((resp) => {
this.myEvents = resp;
});
}
}
```
### Template
```html
```
## Implementation notes
- Render three separate `Eventcalendar` instances on one page in a responsive 3-column grid (`mbsc-col-sm-12 mbsc-col-md-4`), each inside an `mbsc-form-group` with an `mbsc-form-group-title`. Use `view: { calendar: { labels: true } }` for all three. Wrap the page in a `Page` component.
- **Gregorian instance** - no `calendarSystem` needed (Gregorian is the default). Angular and JS/jQuery also pass `locale: localeEn` explicitly; React and Vue omit it.
- **Jalali instance** - pass `calendarSystem: jalaliCalendar` and `locale: localeFa`, both imported from the Mobiscroll package. JS/jQuery: access as `mobiscroll.jalaliCalendar` and `mobiscroll.locale.fa`.
- **Hijri instance** - pass `calendarSystem: hijriCalendar` and `locale: localeAr`, both imported from the Mobiscroll package. JS/jQuery: access as `mobiscroll.hijriCalendar` and `mobiscroll.locale.ar`.
- Load events once from `https://trial.mobiscroll.com/events/?vers=5` via JSONP using `getJson(url, callback, 'jsonp')`. Angular: use `HttpClient.jsonp()` instead. For state-based frameworks, share one reactive events array bound to all three instances. For the imperative API (JS/jQuery), call `inst.setEvents(events)` on each of the three instances inside the callback.
